The PDB culture medium was selected to ferment the endophyte strain, and the secondary metabolites of endophytic fungi Penicillium polonicum were studied. Combined application of Sephadex LH-20, ODS and HPLC chromatographies over the ethyl acetate extract of the fermented culture led to the isolation of 6 compounds. By spectral methods, the structures were elucidated as [3, 5-dihydroxy-2-(7-hydroxy-octanoyl)]-ethylphenylacetate (1), (3, 5-dihydroxy-2- octanoyl)-ethyl phenylacetate (2), (5, 7-di- hydroxy-9-heptyl)-isobenzo pyran-3-one (3), 3-(hydroxymethyl) 4-(1E)-1- propen-1-yl-(1R, 2S, 5R, 6S)-7-oxabicyclo [4.1.0] hept-3-ene-2, 5-diol (4), (E)-2-methoxy-3-(prop-1-enyl) phenol (5) and p-hydroxylphenylethanol (6).

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

Objective To analyze the clinical characteristic of acute pancreatitis with hyperlipemia.Methods 276 patients with acute pancreatitis were divided into two groups:hyperlipemia group and normal group under the diagnostic code.The etiological factor and clinical characteristic were compared between the two groups,also the scores of APACHEⅡ,Ranson and CT after control lipid were compared.Results The factor of food and drink and the rate of SAP in group HL compared with those in group normal were significantly different (P

Microbe cell-surface engineering , which use the microbe cell surface display technology to display foreign proteins on the microbe cell surface to produce cell-surface proteins, was developed in recent years. I t can be utilizedto develop cell-catalyst, cell-adsorbent , live vaccine, biosensor and so on, and have a wide application perspective. But in our county, the microbe cell-surface engineering is studied just now. This review explain the development of the microbe cell surface engineering, overview the study and progress of microbe cell-surface engineering, and look this technology into the future.

The protoplasts of Micromonospora purpurea,the high yield strains of gentammicin producer were mutagenized by diethyl sulfate(DES)and ultraviolet radiation(UV)respectively,then fused,screened by gentamicin resistance and regenerated.The average fermentation unit 2200?U/ml could be achieved by shake flask for 10 batches.The average fermentation unit 1900?U/ml could be obtained by 5L fermentor for 7 batches.The quality of the end product conformed to CP2000,BP2000 and USP26 pharmacopoeia.

Objective To compare the survival rate of two kinds of neurovenofasciocutaneous flaps and investigate the venous reverse flow of flaps.MethodsTen New Zealand White rabbits were randomly allocated into 2 groups of 10 flaps(group A: the lesser saphenous sural pedicled fasciocutanous flaps,blood supply provided with perforator arteries;group B: the lesser saphenous sural pedicled fasciocutanous flaps,blood supply provided with axial type artery).The survival rate of flaps in two groups was observed.Pedicles of flaps were harvested and examined histologically.ResultsThe survival rate of flaps in group A was significantly lower than that in group B[(15.2?16.7)% vs(94.1?6.4)%,P
